As witnessed by the unfortunate travails of R2-D2, Star Wars product merchandizing can go horribly awry. So sometimes it's safer to go with a simpler product for branding purposes, even if it means going analog (gasp).
Case in point: These Lego Star Wars Pens as seen on Uber-Review. The set pictured here includes Yoda, Darth Vader, and, yes, even the hapless, chirping R2-D2.
In addition to serving as perfectly serviceable writing instruments, these pens can be dispatched so you can mix and match their various parts while waiting for the next blockbuster arrives from the Lucas Empire. Because there will certainly be plenty of time to kill.
